Keratin and protein base treatments

[EdenHinckley]

What is the difference between the keratin and protein base treatments you can get? Both seem to be to strengthen and make gel polish last longer. Which is better for use under gel polish and do you use acid or non acid primer?

I have literally just removed indigo keratin gel base coat. Gels lasted ages but very difficult to remove and because of the long difficult removal I don't really feel like my nails have benefited from it [emoji53] x

One of my therapists uses it and clients seem to love it. From what I could see the keratin has to be filed off but the protein base soaks off and by description does the same thing. Effectively keratin is a protein so not sure about which is better given the removal xx
